        Students who have worked in foreign-funded enterprises should have this feeling , It seems that foreigners are good at architecture design . In contrast to this , Domestic students seem to be better at writing code . Same design , Foreigners prefer to draw pictures , The text part has , But it is also half of the text and half of the picture ; Domestic students write less documents , I prefer to write code , Even when writing documents, words and tables account for a large part .

        Think about it carefully , There's this difference , There are cultural reasons 、 differences , There are also differences in industrial segmentation , At the same time, there are also differences between eastern and Western working methods . What the West values more is communication 、 synergy 、 The interface is clearly defined ; The East stresses division of labor , Fully functional , Fast forward .

        Take architecture design for example , No matter at the business level , Or technical level , Painting is indispensable . But the purpose of drawing is to build the model , Dig out the main contradiction of the problem 、 Main process , Not to draw a picture . If architecture design just stays on paper , Unable to land , That really became ppt Architect .

1、 Architects are not suitable for novices who just work

        For starters , Maybe this part of personal development software is not very familiar , I don't know about business , It's not suitable to be an architect at this time . It's best to wait until you have some work experience , such as 3~5 It is more appropriate to become an architect slowly after 20 years .

2、 Architects are not the end of their careers

        To put it bluntly , Architects just translate requirements into software modules one by one 、 Software subsystem 、 Even across pc Distributed systems , Extract the interface and main process . Specific module development also depends on engineers and development teams . Even if the architect is ready , His work also needs the cooperation of others , To make a finished software product .

3、 Software architects need to write their own code

        If the architect doesn't write code himself , He has no way to know the complexity of the problem , There is no way to evaluate the development time of software modules , So generally speaking, architects need to write their own code .

4、 Communication is for architects , As important as technology

        Architecture design is essentially an art of compromise , It needs manpower 、 Time 、 cost 、 Accumulation of knowledge 、 Complexity and other conditions . From this point of view , He needs to communicate with different people , For example, communicate with product economy , Communicate with developers , Communicate with the project manager, etc , therefore , Communication is very important for architects .

5、 Abstract ability is an important criterion to distinguish architects

        A lot of people don't understand , Why should object-oriented have polymorphism . Actually , This is mainly because I don't understand software engineering . In the process of software development , For various functions , We must find a way to extract the main process . Besides , After the software is developed , Generally, there will be all kinds of new changes , If you have no abstract ability to the original logic , For these new requirements, if only the method of patching is used to solve , Code quality will only get worse , Finally, there is no way to use and maintain .

6、 The architecture diagram is the final output of the architect

        From the complex requirements , Build a reasonable framework , Until the final code generation 、 Compile and deploy , This part requires a lot of architecture diagrams .uml Figure is a good method . The architecture is at the module level and in key sub functional areas , Each of these uml Pictures can be taken and used . for instance , The state machine does not mean that the high-level module is used , Low level development cannot be used , No such thing .

  

          In the actual architecture process , Don't have any ideological baggage , Other pictures can also be drawn , For example, the structure diagram 、 Swimlane diagram 、 Brain map 、 fishbone diagram 、 Gantt Chart 、cad chart 、 Chart 、 Topology and so on , These can be used . What I use more personally is openoffice Of draw Software , Some people like it processon, It's all right .

        Even the circuit diagram , It can also be completed by architecture design , such as soc Core board

7、 The architecture also needs to be updated in time

        The reason why many students don't like writing documents is that the code updates quickly , Sometimes it is troublesome to update to the document . But the architecture is the same , If there are new changes that are not updated in time , Then architecture will eventually lose its meaning , No one will look at an outdated architecture diagram and document .

8、 Architecture is discussed

        Many people talk about architecture , Not necessarily . Most of the time, architecture is discussed . First , The knowledge of architects also has certain limitations , Besides , The discussed architecture has less resistance to implementation ; Finally, since it is a discussion , There will be a process of persuasion and persuasion , This requires architects to have a global vision , Before actual development, you must reconsider your own architecture design , There are no obvious loopholes , So as not to make people laugh .

        Besides , Many students think that architecture is made behind closed doors , Put the design pattern 、uml、java Open source framework 、 Three layer architecture 、 Do it in blocks and layers , You can do architecture design , It's not right . Architecture comes from business , It is also constantly adjusted , It is impossible to apply the template directly . The part mentioned above is only the meaning of operation , Essence is still the refinement of needs 、 Modeling and abstraction . This is the purpose of never changing , Is the starting point of all work .

9、 Architecture is not framework plus edition

        Architecture is business centric , Not framework centric . The architecture is finalized , What frame is suitable for what frame , Never have preconceived concepts . I can use rtos, For all projects rtos. This will only add to your troubles , Let the development students at a loss , It deviates from the original intention of architecture design .

10、 Architecture allows you to have a holistic view 、 Close to money 、 Let more people work for you

        There are many factors to consider when building an architecture , At this time, you will be required to consider all aspects . A thoughtless , We're going to push it over again , This is also a common thing . Another one is embarrassed to say , Software architecture is often about solutions 、 Out method , Compared with writing code , Software architects are much closer to money . meanwhile , With an overall vision , Architects can also arrange others to work , Constantly expand your ability boundaries , This is also not comparable to ordinary programmers . therefore , Generally speaking , The income of architects is much higher than that of ordinary programmers , That's one of the reasons .
